/* =========================================================================
   Vulnerability-Lookup — "Analyst console" theme
   -------------------------------------------------------------------------
   A token-driven layer on top of Bootstrap 5.3. Wherever possible we steer
   Bootstrap through its own --bs-* custom properties (scoped per
   data-bs-theme) so components stay consistent instead of being overridden
   one selector at a time. Brand colours are preserved:
       slate  #446d80  → chrome, primary actions
       azure  #006FBA  → links, accents, focus
   The signature element is the "signal line": a thin slate→azure seam pinned
   to the top of the page and echoed on nav hover and key card accents.

/* ##### Vulnerability description ##### */

/* Descriptions are plain text, but roughly one CVE in five wraps its own lines,
   and the sources built from mailing-list archives carry entire advisories --
   headings, bullet lists, numbered reproduction steps. `pre-wrap` is what keeps
   that structure readable instead of collapsing it into one run of prose; the
   `render_summary` filter is what makes it safe to do, since it escapes the
   whole description and emits nothing but anchors around bare http(s) URLs.

   `break-word` is for those posts' long unbroken URLs, which would otherwise
   push the card wider than the page. */

/* ##### CVSS vectors ##### */

/* A vector string is one long token with no spaces in it, and the severity
   cards that carry it are flex items, whose automatic minimum size is the
   min-content width of their contents -- so on a narrow screen the card
   refuses to shrink and the vector runs out of the page. Firefox happens to
   offer a break after each slash of its own accord, Chrome does not, which is
   why the overflow only showed up there.

   The metric-aligned breaks come from the `<wbr>` the `cvss_vector_breaks`
   filter puts after every slash; this rule is the fallback under them, for a
   segment too long to fit on a line of its own. `anywhere` rather than
   `break-word` because only the former is counted when min-content is
   computed: with `break-word` the card would still refuse to narrow, and the
   vector would still hang out of it. */
